Description

  The present invention relates to defibrillators and, more particularly, to automatic external defibrillators (AEDs).

  Resuscitation for patients with cardiac arrest generally involves cleaning and opening the patient's airways, applying artificial respiration to the patient, and applying chest compressions to the patient's heart, brain and other important Including providing blood flow to the organ. Resuscitation can also include defibrillation therapy if the patient has a shockable heart rhythm.

  There are many different types of abnormal heart rhythms, some of which can be treated with defibrillation therapy ("shockable rhythm") and some cannot be treated ("unshockable rhythm"). For example, most ECG rhythms that produce significant cardiac output are considered non-shockable rhythms (examples include normal sinus rhythm, specific bradycardia, and sinus tachycardia). There are also various ECG rhythms that have not produced significant cardiac output but are still considered unshockable. This is because defibrillation therapy is usually ineffective under these circumstances. Examples of these unshockable rhythms include cardiac arrest, electromechanical dissociation and other pulseless electrical activities. Patients will not be able to maintain life with these non-viable, non-shockable rhythms, and applying a shock will not help change the rhythm. The main examples of shockable rhythms that a caregiver should defibrillate include ventricular fibrillation, ventricular tachycardia, and ventricular flutter.

  After using a defibrillator to deliver one or more shocks to a patient with a shockable ECG rhythm in a shockable or non-shockable rhythm, perfusion or non-perfusion rhythm, the patient nevertheless It may remain unconscious. In the presence of non-perfusion rhythm, the caregiver takes measures to perform CPR for a period of time to provide continuous blood flow and oxygen to the patient's heart, brain and other vital organs. If a shockable rhythm continues to exist or continues to occur during CPR, further defibrillation attempts are undertaken following this stage of cardiopulmonary resuscitation. If the patient remains unconscious and does not have effective blood circulation, the caregiver can use a defibrillator (analyze the electrical rhythm and possibly shock) and cardiopulmonary resuscitation ( CPR) is performed alternately. In general, CPR involves a repetitive pattern in which two or more artificial breaths are given after 5 or 15 chest compressions.

  Defibrillation can be performed using an AED. The American Heart Association, the European Resuscitation Council and other similar institutions provide protocols for the treatment of cardiac arrest patients, including the use of AED. These protocols define a series of treatments that follow the patient's status and determine the appropriate treatment to be administered during resuscitation. Caregivers who need to use AEDs are trained to follow these protocols.

  Most automatic external defibrillators are actually semi-automatic external defibrillators (SAEDs) that require the caregiver to press a start button or an analysis button. The defibrillator then analyzes the patient's ECG rhythm and advises the caregiver to shock the patient if the electrical rhythm is shockable. Then, the caregiver presses a control button for giving a shock. Following the application of the shock, the SAED automatically or manually reanalyzes the patient's ECG rhythm and advises additional shocks or asks the caregiver (whether the defibrillation treatment was successful or the rhythm The patient's circulatory sign is checked (if the patient cannot be shocked) and if the defibrillation attempt does not restore circulation, he is instructed to begin CPR. On the other hand, fully automatic external defibrillators do not wait for user intervention before delivering a defibrillation shock. As used below, automatic external defibrillators (AEDs) include semi-automatic external defibrillators (SAEDs).

  In general, both types of defibrillators will sound a “Please leave” warning before the start of ECG analysis and / or before each shock is applied. The caregiver then needs to depart from the patient (ie, stop any physical contact with the patient) and press a button to give a shock. The controls for automatic external defibrillators are generally located on a resuscitation control box.

  In general, AEDs are used by trained medical caregivers or medical caregivers such as doctors, nurses, lifesaving personnel, firefighters, and police officers. Caregivers trained to prepare AEDs on site and operate AEDs are important. This is because the patient's chances of surviving cardiac arrest are reduced by approximately 10% every minute between the occurrence of arrest and the delivery of defibrillation therapy.

  Trained general caregivers are a new group of AED operators. For example, a spouse of a patient having a heart attack may be trained as a general caregiver. General caregivers rarely have the opportunity to perform defibrillation or CPR. For this reason, the general caregiver is easy to atrophy with respect to AED at the time of medical emergency. Therefore, such general providers may be reluctant to obtain an AED or use an AED when necessary, and fear that they may make a mistake. May tend to wait for the arrival of an ambulance rather than using an available AED.

  Some of the trained health care providers, such as specialists such as obstetricians, dermatologists, and general practitioners, rarely have the opportunity to perform CPR and / or defibrillation, You might be worried about doing it. If training is rare, competence concerns may be adversely affected and the caregiver may not be able to remember all of the recommended resuscitation protocol steps and / or their exact order Worry not.

  Similarly, both medical caregivers and general caregivers may hesitate to give CPR and artificial respiration, especially when their training is rare and they rarely use it You may not be confident when these steps should be performed.

  In the present invention, a graphical user interface for using an AED is provided. The graphical user interface includes a set of graphics that clearly show the steps to be performed by a caregiver trained to resuscitate a cardiac arrest patient. Visual support and encouragement of trained caregivers who may feel incapacitated to perform cardiac resuscitation, including the use of AED, with graphics with voice calls and / or visually displayed messages Advice is provided. For caregivers who are confident in their training and skills, visual arousal can help the caregiver to perform the required steps of the resuscitation procedure more quickly and efficiently.

The graphic shows a picture configured to alert the caregiver to check the patient's reaction, a picture configured to alert the caregiver to call for emergency assistance, and the patient's airway. A picture configured to alert the caregiver to open, a picture configured to alert the caregiver to check the patient's pulse, and alert the caregiver to attach the electrode to the patient A picture configured to remind the caregiver to leave the patient and a caregiver to press the treatment button so that the defibrillator applies a defibrillation shock One or more of a picture configured to do and a picture configured to alert the caregiver to perform CPR. Preferably, the picture shows how the steps should be performed, e.g. how to open the airway, where the electrodes should be attached, how to perform chest compressions and artificial respiration Illustrated.

  In general, if the defibrillator is a SAED, the defibrillator further includes a treatment button configured to be depressed by the caregiver so that the defibrillator applies a defibrillation shock. The position of the treatment button may be indicated by a graphic such as a heart symbol.

  In one embodiment, the defibrillator further includes a light source associated with each of the series of graphics. The defibrillator may include an electronic device configured such that the light source emits light sequentially. The sequence of light emission may be controlled by an electronic device configured to measure the time elapsed since the caregiver turned on to activate the defibrillator, at least some of the light sources Light is emitted sequentially based on the elapsed time. Alternatively or in addition, the sequence of emissions may be controlled by an electronic device configured to program with time for light source emission, at least some of the time being ( Based on the time elapsed since the previous light source first emitted in the procedure, or (b) the shock was delivered to the patient. The series of light emissions of some of the light sources may be controlled by an electronic device configured to capture data from the electrodes, and at least some of the light sources are sequentially based on the data captured from the electrodes. Emits light. The light source may emit light based on an algorithm, for example, the algorithm may include: (a) the time elapsed since the previous light source first emitted in the procedure; and / or (b) the last time a shock was delivered to the patient. One or more data items of time elapsed from time and / or (c) result of ECG analysis are taken into account.

  In one embodiment, the defibrillator also includes an electronic device configured to provide voice alerts to the caregiver. The sound arousal can be timed in any of the ways described above associated with a series of light emission of light sources. In general, voice calls are associated with a series of graphics and are given sequentially to guide the caregiver through a series of steps. The sound arousal is also associated with a series of light emission of the light source.

  At least some of the graphics are provided on the cover portion of the defibrillation control box. These figures are provided on the inside and / or outside of the defibrillator cover. If graphics are provided on the outside of the cover, they may include a picture indicating that the cover should be removed from the defibrillator. The cover may include a space provided for regional emergency information, for example, a window in which a card on which regional emergency information is written can be placed.

The graphic can be provided in any desired form, for example, in the form of a translucent image with backlight, as an electronic display, or in the form of a transfer mark.
In another aspect, the invention features a system that alerts a caregiver to a resuscitation procedure for a patient who will have cardiac arrest. The system includes: (a) an electrode configured to capture data indicating whether the patient's heart rhythm and electrodes are properly positioned on the patient; and (b) a defibrillation control connected to the electrodes. To analyze the data received from the electrodes and measure the time elapsed since the defibrillation control box was activated by the caregiver and / or since the last shock was given to the patient To display information relating to the appropriate steps of the resuscitation procedure to be performed by the caregiver at a specific time based on the defibrillation control box configured in (c) and the data received from the electrodes and the elapsed time And a user interface configured.

  In yet another aspect, the present invention provides: (a) an electrode attached to a patient and configured to capture data indicative of the patient's heart rhythm and deliver a defibrillation shock when appropriate; and (b) an electrode A defibrillation control box connected to the instrument, and (c) a treatment button configured to be depressed by a caregiver to deliver a defibrillation shock, the position of the treatment button being indicated by a heart symbol A treatment button and (d) an electronic device configured to temporarily illuminate the heart symbol when a shock is recommended based on an ECG analysis performed by the defibrillation control box Features a motive.

  In a preferred embodiment, a graphical interface illustrates the entire procedure of resuscitation activity recommended by the American Heart Association. As a result, the graphical interface helps both experienced and unskilled users to achieve the initial steps of patient treatment included in the AHA resuscitation protocol.

  In addition, because a picture is worth a thousand words (a hundred is just a glance), the graphic interface reminds the caregiver how to perform the steps of the AHA resuscitation protocol. . For example, rather than simply “checking the respiratory tract” being urged by the caregiver, the graphic interface means that the caregiver should perform a head-back flexing maneuver. I remember what it meant. Just using voice or text arousal to provide the same information will flood the caregiver with detailed information that will confuse the caregiver. The graphical interface allows caregivers to use their vision to remember what to do at each step in the rescue. Also, the picture is useful when rescue is being performed in a noisy environment where the voice arousal is almost inaudible.

  Other features and advantages of the invention will be apparent from the description, drawings, and claims.

  As shown in FIG. 1, the automatic external defibrillator 10 includes a removable cover 12 and a control box 14. The defibrillator 10 is shown in FIG. 2 with the cover 12 removed. An electrode assembly 16 (or a pair of separate electrodes) is connected to the control box 14 by a cable 18. The electrode assembly 16 is stored under the cover 12 when the defibrillator is not in use.

The control box 14 includes a power button 15 and a status display unit 17. The status display 17 informs the caregiver whether the defibrillator is ready for use.
The cover 12 includes a cover transfer mark 20 (FIGS. 1 and 3) that includes a logo 22 and a series of graphics 24, 26, and 28. The logo 22 may provide information regarding the manufacturer of the device and that the device is a defibrillator (eg, “ZOLL AED” as shown in FIG. 3 is a Zoll Medical device). ) Is a semi-automatic external defibrillator available from Figures 24, 26, and 28 lead the caregiver to the early stages of the cardiac resuscitation procedure outlined in AHA's AED procedure algorithm for emergency heart procedures up to the arrival of emergency medical staff ("care resuscitation and (See Guidelines 2000 for Emergency Cardiovascular Treatment, Circulation Appendix, Volume 102, Number 8, August 22, 2000, pages 1 to 67.) Figure 24 showing caregivers and patients provides care It has been shown that a person should first check the patient's reaction, for example by gently shaking the patient and asking if it is okay, followed by a call 26 and a graphic 26 showing an emergency vehicle. It has been shown that a person should call for emergency assistance before performing resuscitation, and finally figure 28 shows this. The caregiver should turn on the power by removing the defibrillator lid 12, removing the electrode assembly 16 stored under the lid, and pressing the button 15. The figures are arranged in a clockwise order so that the first step is located in the upper left, because this is the order that most caregivers will understand intuitively. However, in this case, the order of steps performed by the caregiver is not important, and therefore any other indication of the order of steps may be provided for ease.

  The cover includes a slot 28 (FIG. 1) into which a card containing local emergency information can be inserted, and a transparent window 30 attached to the slot 28 through which the card can be seen. Alternatively or in addition, this information may be added to the cover by the user and displayed on the transfer mark, for example, a telephone number added to the area 34 (FIG. 3) of the cover transfer mark 20 There is a transfer mark 32 (FIG. 1). These features allow emergency information to be customized for a specific region and easily updated if there is a change.

  The control box includes a control box transfer mark 40 shown in FIGS. Similar to the transfer mark 20, the transfer mark 40 includes a series of figures 42 to 49 (FIG. 4). In this case, as will be described later with reference to FIG. 5, the graphic is configured to guide the caregiver through the entire resuscitation procedure. The transfer mark 40 also includes a central graphic 50 that includes a representation of the hand 52 and heart 54 (FIG. 4). The central graphic 50 is disposed on a treatment button that provides a defibrillation shock to the electrode assembly 16 on the defibrillator when pressed.

  Each graphic on the control box transfer mark 40 is fitted with a light source capable of temporarily emitting light to indicate that the illuminated step should be performed at that time. These light sources guide the caregiver step by step through the resuscitation procedure and indicate which graphics should be seen at each point during the resuscitation.

  The light source for each of the graphics 42-49 is preferably a proximity LED (LED 56, FIG. 2). The heart 54 is translucent and may be illuminated from behind by a light source (not shown) provided in the control box. Alternatively, the heart 54 may include a proximity LED (not shown) and / or the hand 52 may include an LED 57 as shown.

  The LEDs 56 and 57 are mounted on the control box and are visible through an opening provided in the transfer mark 40. As will be described in more detail below, when the heart 54 and / or hand 52 is illuminated, this causes the care button to be depressed to provide a defibrillation shock. It should be shown.

Programmable electronics provided in the control box 14 are used to determine when each of the light sources should emit light.
The light emission of the LEDs adjacent to the figures 42 to 45 and the subsequent turn-off are based on the time elapsed since the caregiver pressed the button 15 to turn on the power. The elapsed time is measured by a programmable electronic device and is used for each of the LEDs associated with the graphics 42-45 to emit light in turn. In order to give the caregiver the appropriate time to perform each step, an elapsed time of about 2-15 seconds is assigned between each light emission. These time intervals vary from a few seconds for graphic 42 (check response) to 10 seconds or more for graphic 44 (open airway, check breathing).

  The light emission of the LED proximate to the graphic 46 is based on the elapsed time, but the subsequent extinguishing of this LED indicates that the impedance measured by the programmable electronics is such that the electrode of the electrode assembly 16 is properly placed on the patient Based on whether or not This LED remains lit until the correct impedance between the electrodes (eg, less than 300 ohms) is detected.

  As will be described later with reference to FIG. 5, the lighting and extinguishing of the LEDs near the graphics 47-49 and the light behind the heart 54 is based on ECG data captured by the electrode assembly 16 and analyzed by programmable electronics.

As will be described later with reference to FIG. 5, a programmable electronic device may provide voice alerts that are timed with the light emission of the light source.
FIG. 5 in the form of a flow chart shows the use of the graphic on the transfer mark 40, accompanied by visual and audio alerts by the caregiver performing the resuscitation. The text performed in the box shows the steps performed by the caregiver. The text in the speech bubble with the ear symbol indicates the speech arousal produced by the defibrillator.

  When a person falls and the caregiver suspects that this person is in cardiac arrest (100), the caregiver first secures the defibrillator and turns on the power (102). When the unit has completed its internal self-test and is ready for use, this is displayed on the display 17 as described above. Next, the defibrillator alerts the caregiver to a pre-speech message such as “Please calm down and listen carefully” (voice alert 104).

  Shortly thereafter, the defibrillator alerts the caregiver that the caregiver should check the patient's response (speech 106). At the same time, the LED adjacent to the graphic 42 is lit and instructs the caregiver to see this graphic. In order to determine whether or not the patient is unconscious from the graphic 42, the caregiver shouts “Are you okay?” And instructs the caregiver to shake the person (step 108). ).

  After an appropriate amount of time (eg 2 seconds), the defibrillator will help the caregiver if the caregiver has not turned off the defibrillator (even if the patient responds). A voice call is given indicating that the call should be sought. At the same time, the LED adjacent to the graphic 42 is turned off, the LED adjacent to the graphic 43 is turned on, and the caregiver's attention is directed to the graphic 43. If the caregiver has not yet called the emergency staff, the caregiver is reminded to call the emergency staff by means of the graphic 43 (step 112).

  After the caregiver has performed step 112 at appropriate intervals (eg, 2 seconds from voice awakening 110), the defibrillator causes the caregiver to open the patient's airway and check if the patient is breathing. A voice call is given indicating that it should be (voice call 114). The LED adjacent to the graphic 43 is turned off, and the LED adjacent to the graphic 44 is lit, causing the caregiver's attention to be directed to the graphic 44 indicating the appropriate procedure for opening the patient's airway. Thus, the caregiver is guided to lift the patient's chin and tilt the patient's head backward (step 116). As will be described below with reference to FIG. 7, the caregiver may place an airway support device under the patient's neck and shoulders as needed. The caregiver then performs a check to determine if the patient is breathing.

  After a suitable interval (eg, 15 seconds from voice alert 114), the defibrillator gives a voice alert that the caregiver should check for signs of circulation (voice alert 118). The LED adjacent to the graphic 44 is turned off, and the LED adjacent to the graphic 45 is lit. The graphic 45 indicates to the caregiver that the patient's pulse or other signs of circulation should be checked as recommended by the AHA for general rescuers.

  After a suitable interval (e.g., 5 to 7 seconds from the sounding 118), the defibrillator provides a sounding that indicates that the caregiver should attach the electrode assembly 16 to the patient (sounding). Arousing 122), the LED proximate to the graphic 45 is extinguished and the LED proximate to the graphic 46 is lit. Graphic 46 indicates to the caregiver how the electrode assembly 16 should be placed on the patient's chest (step 124). The defibrillator periodically repeats the sounding 122 every 15 seconds until the electrodes are properly connected to the patient.

  When the impedance data received from the electrode assembly indicates that the electrode is properly positioned and in contact with the patient's skin, the defibrillator stops the sounding 122 and approaches the graphic 46. The LED is turned off. At this point, the LED in proximity to the graphic 47 is turned on, and the defibrillator has analyzed the patient's heart rhythm with the defibrillator and a voice call (instructed that the caregiver should leave) A voice call 126) is given. While this LED is lit, the defibrillator captures ECG data from the electrode assembly and analyzes the data to determine if the patient's heart rhythm is shockable. This analysis is performed conventionally by AED.

  If the defibrillator determines that the patient's heart rhythm is not shockable, the defibrillator gives a voice alert such as “Shock is not recommended” (voice alert 128). Then, the LEDs adjacent to the figures 48 and 49 are lit, the defibrillator opens the patient's airway again, checks the breathing and pulse, and if no pulse is detected by the caregiver, the CPR is A voice call is given indicating that it should start (voice call 130, step 132). With graphics 48 and 49, the caregiver is reminded of the appropriate steps to take when applying CPR.

  Alternatively, if the defibrillator determines that the patient's heart rhythm is shockable, the defibrillator will sound “Short shock recommended. Please leave the patient. Press the treatment button.” A call is given (voice call 134). At the same time, the heart 54 and / or the hand 52 are lit to inform the caregiver of the location of the treatment button. At this point, the caregiver leaves (warns others to leave, if any), presses the heart 54, presses the treatment button, and gives the patient a defibrillation shock (or defibrillation). A series of shocks determined by the electronic equipment of the vessel is applied (step 136).

  After step 136 is performed, the speech evoking 126 is again provided and the patient's heart rhythm is automatically analyzed by the defibrillator while the graphic 46 is illuminated again. If a shockable rhythm is repeatedly detected, or until the defibrillator is turned off or the electrode is removed, the above analysis and shock procedure is repeated up to three times. After the third shock, LEDs 48 and 49 are emitted by the device, and a sound alert 130/132 is emitted. The device maintains LEDs 48 and 49 in a light emitting state for about one minute, indicating that if CPR is taking place, CPR should continue for one minute. In order to instruct the user to continue chest compressions and artificial respiration, the voice prompt “continue CPR” is repeated every 15 to 20 seconds during this period.

  After about 1 minute, the LEDs 48 and 49 are turned off by the device, and the LED 47 is turned on. A voice call 126 (please leave, analyzing rhythm) is also issued and a new procedure for ECG analysis / shock up to 3 times is started.

  If the caregiver detects circulation during step 132, the caregiver may turn off the defibrillator and / or remove the electrodes. Alternatively, the caregiver may not perform further CPR but nevertheless allow the device to re-analyze the ECG after each one minute CPR period and perform repeated periodic monitoring to ensure that the patient is shocked. You may make it confirm that it has an impossible rhythm.

  Thus, if a shockable rhythm continues to exist, three ECG analyzes and three shock procedures will follow indefinitely followed by one minute of CPR. Instead, if there is a non-shockable rhythm or if it becomes a non-shockable rhythm, the procedure would be Analyze / Shock Not Recommended, 1 Minute CPR, Analyze / Shock Not Recommended, 1 Minute CPR, etc. . When a shock was effective in changing a patient's heart rhythm to a heart rhythm that does not require further defibrillation treatment, the procedure is: analysis / shock recommendation, shock (rescue patient), analysis / shock recommendation 1 minute CPR period (if a pulse is detected, the caregiver does not perform CPR during this period), analysis / shock deprecation, 1 minute CPR period, etc. Continue until it is switched (eg, when the caregiver detects a pulse) or until the electrode is removed.

  If the electrode is no longer contacted at any time (determined by the impedance data received from the electrode assembly), an appropriate audible alert such as “Check the electrode” and the LED near the graphic 46 Luminescence occurs.

Other embodiments are within the scope of the claims.
For example, a desired light source may be attached to the graphic on the central transfer mark. For example, according to preference, all figures may be translucent or backlit. Alternatively, the graphic may be provided in the form of an LED image instead of a transfer mark.

It is preferred that audio arousal and visual (light source) arousal be used, but these features may be omitted if desired.
Although the electrodes are illustrated in the form of an integral electrode assembly, separate electrodes may be used.

  In the preferred embodiment, all of the graphically depicted steps are shown simultaneously, as illustrated, for example, by the transfer marks described above. This arrangement allows the caregiver to see the next step to take and thus anticipates the next step and initiates it early if possible. However, instead of this, for example, by using a screen that displays one figure at a time or a figure with a backlight that cannot be distinguished when not illuminated from the back, one figure is displayed at a time. Also good. In some cases, this configuration avoids confusing beginners or ordinary rescuers. This is because it does not give the caregiver all the excess information at the same time.

If desired, each graphic may have an associated button that, when pressed, causes the defibrillator to output a more detailed voice call related to that graphic.
The cover 12 of the AED may include a transfer mark such as the transfer mark 200 shown in FIG. Transcription mark 200 illustrates the use of the cover as a passive airway support device to keep the patient's airway open during resuscitation. The graphic 202 alerts the caregiver to tilt the patient and place the cover 12 under the patient's shoulder. Graphic 204 shows the proper positioning of cover 12 under the patient to ensure an open airway.

  Although not included in the transfer mark shown in FIG. 4, the transfer mark 40 may include a graphic that prompts the user to check to see if the patient is breathing. Such a graphic may include, for example, a picture of a caregiver whose ear is adjacent to the patient's mouth. The graphic may include a line indicating the flow of air from the patient's mouth.

  In this specification, the terms “light”, “light” and similar terms are used for both stationary and flashing light. If necessary, flashing light may be used to draw the user's attention more clearly to the associated graphic.
